At the new United, we treat all elites alike!

As far as elite boarding goes, they're basically going back to the PMCO protocol.
If I had to venture a guess, I'd say GA's complained that, with the overwhelming workload imposed on them by SHARES, they sought a simplification of the boarding process.
